BorderLayout – Java Swing – Example

In this tutorial, we are going to see an example of BorderLayout in Java Swing. BorderLayout is used to arrange the components into five regions: north, south, east, west, and center. Each region (area) can contain only one component. This is the default layout of the frame or window. BorderLayout provides five constants for each region:

• public static final int NORTH
• public static final int SOUTH
• public static final int EAST
• public static final int WEST
• public static final int CENTER

 
 
BorderLayout constructors class:

BorderLayout Constructor	Description
JBorderLayout()	Creates a border layout but without spaces between components.
JBorderLayout(int h, int v):	Creates a border layout with the specified horizontal and vertical spaces between the components.
